Mini Impatiens plant named ‘Immipink’

ABSTRACT

A new and distinct cultivar of mini  Impatiens  plant characterized by its small rose flowers, freely flowering habit, dark green foliage, and bushy shaped growth habit with excellent basal branching.

Latin name of the genus and species of the plant claimed: Impatiens walleriana.

Varietal denomination: ‘Immipink’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct mini Impatiens plant botanically known as Impatiens walleriana and referred to by the cultivar name ‘Immipink.’

The new cultivar was developed in a controlled breeding program in Beit Dagan, Israel. The new mini Impatiens cultivar is characterized by small rose flowers, freely flowering habit, dark green foliage, and bushy shaped growth habit with excellent basal branching.

The new cultivar is propagated from cuttings resulting from the cross in March 1998 of the proprietary mini Impatiens selection identified as ‘FRA 301’ as female parent and the proprietary mini Impatiens selection identified as ‘BGA 310’ as male parent. ‘FRA 301’ is not commercially available and has not been patented. ‘BGA 310’ is not commercially available and has not been patented.

As a result of this cross the present cultivar was selected in February 1999 in Beit Dagan, Israel and has been repeatedly asexually reproduced by cuttings over a period of several years. The distinctive characteristics of this new mini Impatiens are stable and reproduced true to type in successive generations of asexual reproduction. It takes 6 to 8 weeks to produce a finished plant, starting from a rooted plug and planted in a 10 cm pot, depending on the temperature.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Immipink.’ These characteristics in combination distinguish ‘Immipink’ as a new and distinct mini Impatiens cultivar:

-   -   1. Small rose flowers     -   2. Bushy shaped growth habit with many flowers on top of the         foilage     -   3. Dark green foilage     -   4. Excellent basal branching

Plants of the new mini Impatiens differ primarily from the plants of the female parent selection in the following characteristics:

Plants of the new mini Impatiens have small rose flowers, whereas the plants of the female have small pink flowers.

Plants of the new mini Impatiens differ primarily from the plants of the male parent selection in the following characteristics:

Plants of the mini Impatients have small rose flowers, whereas the plants of the male have larger, pink flowers.

Plants of the new mini Impatiens can be compared to plants of ‘Fify lav,’ disclosed in U.S. Plant Pat. No. 11,821. In side-by-side comparisons in Enkhuizen, Netherlands, the plants of the new mini Impatiens differed from plants of the cultivar ‘Fify lav’ in the following characteristics:

-   -   1. Plants of the new mini Impatiens have dark green leaves,         whereas plants of the cultivar ‘Fify lav’ have green leaves     -   2. Plants of the new mini Impatiens have rose flowers, whereas         the cultivar ‘Fify lav’ has lavender flowers.

DESCRIPTION OF THE DRAWING

This new mini Impatiens plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color showing being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new mini Impatiens. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 20 week old plants, blossomed under natural light in the field.

Color readings were taken in the laboratory under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
